Hey guys
I am building a page for myself and friends that will clean up html using php tidy

It works fine but I can not figure out hot to ad indents to the outputed html. I am very new to the tidy workings. here is the code i am using

<?php

$file= $_POST['file'];


$tidy = tidy_parse_string($file);
$tidy->_error_count;


    echo "The following errors were detected:<br>";
    

preg_match_all('/^(?:line (\d+) column (\d+) - )?(\S+): (?:\[((?:\d+\.?){4})]:)
?(.*?)$/m', $tidy->errorBuffer, $tidy_errors, PREG_SET_ORDER);

$malestr = str_replace("line","\nline:",$tidy->errorBuffer);

$article1=nl2br(htmlentities($malestr));
echo "$article1<br>";

$tidy->CleanRepair();
  
echo"<textarea cols=\"80\"rows=\"30\">$tidy</textarea>";
?>

I will feel dumb if it is an easy fix but please if you can tell me how.
I have been trying for hours now.

Since no one has answered this and that is strange on this form I thought that I would share the answer now that I figured it out.

<?php

$file= $_POST['file'];


$tidy = tidy_parse_string($file);


$tidy->diagnose();
    echo "The following errors/warnings were detected:<br>";
    

preg_match_all('/^(?:line (\d+) column (\d+) - )?(\S+): (?:\[((?:\d+\.?){4})]:)
?(.*?)$/m', $tidy->errorBuffer, $tidy_errors, PREG_SET_ORDER);

$malestr = str_replace("line","\nline:",$tidy->errorBuffer);

$article1=nl2br(htmlentities($malestr));
echo "$article1<br>";
ob_start();

echo"$file";

$html = ob_get_clean();
// Specify configuration
$config = array(
          'indent'         => true,
          'output-xhtml'   => true,
          'wrap'           => 200,
          'doctype'        => Transitional
);

// Tidy
$tidy = new tidy;
$tidy->parseString($html, $config, 'utf8');
$tidy->cleanRepair();

// Output
echo"<h2>Here is your cleaned html</h2>";
echo"<textarea cols=\"80\"rows=\"30\">$tidy</textarea>";
?>

hope it can help someone.

I don't know anything about tidy, but if you want tabs and lines to appear in your output use the \t \n characters:

PHP Code:

echo "\t"; //tab
echo "\n"; //new line 


Note that using double quotes is mandatory, using single quotes will output the literal \t and \n.

I have played with the code and got something that works very well it will give a textarea with a list of all errors found and a text area with the html corrected to XHTML1.0 trans and the second text area even auto highlights on mouse click.

I did not know tidy but a crash course helped some.

<?php

$file= $_POST['file'];


$tidy = tidy_parse_string($file);


$tidy->diagnose();
    echo "The following errors/warnings were detected:<br>
<textarea cols=\"80\"rows=\"30\"onclick=\"javascript:select();\">";
    


echo tidy_get_error_buffer($tidy);
/* or in OO: */
echo $tidy->errorBuffer;

echo"</textarea>";
ob_start();

echo"$file";

$html = ob_get_clean();
// Specify configuration
$config = array(
          'indent'         => true,
          'output-xhtml'   => true,
          'wrap'           => 200,
          'doctype'        => Transitional
);

// Tidy
$tidy = new tidy;
$tidy->parseString($html, $config, 'utf8');
$tidy->cleanRepair();

// Output
echo"<h2>Here is your cleaned html <br>(W3C//DTD XHTML 1.0 Transitional)doc type</h2>";
echo"<textarea cols=\"80\"rows=\"30\"onclick=\"javascript:select();\">$tidy</textarea>";
?>

I hope this code can be of help to others.
